FIELD OF THE INVENTION

[0001] The present invention relates to a method for the enhancement of diffusivity and long-lasting property of fragrance, an agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition, a fragrance composition having an excellent diffusivity and long-lasting property and a cosmetic, toiletry, bath composition, food and drink and pharmaceutical having an excellent diffusivity and long-lasting property of fragrance comprising these ingredients.

BACKGROUND ART

[0002] In order to prepare an excellent fragrance composition by blending aroma materials or blend such a fragrance composition with various products, various fixatives have been hitherto used for the purpose of allowing the fragrance composition and various products to keep diffusivity of desired fragrance and adjusting the fragrance properties and long-lasting property of aroma materials. Known fixatives include various compounds such as dipropylene glycol, triethyl citrate, benzyl benzoate, benzyl salicylate and diethyl phthalate. These compounds have heretofore been incorporated in fragrance compositions or various products. However, mere use of these fixatives is not sufficient for the adjustment of volatility and long-lasting property of aroma components and fragrance compositions. Some of these fixatives have safety problem. Thus, studies have been made to obtain fixatives having an excellent diffusivity and long-lasting property of fragrance and causing no safety problem. As fixatives having these properties there have recently been proposed p-menthane-3,8-diol (Japanese Patent No. 3,045,562), 2-hydroxymethyl-cycloalkanol derivative (JP-A-5-295388), and specific biphenyl compounds (JP-A-7-62383). (The term “JP-A” as used herein means an “unexamined published Japanese patent application”.)

[0003] While these references of prior art have reference to the results of long-lasting property test on fragrance compositions made organoleptically on blotter, there is no reference to the fixing effect in products (e.g., cosmetic, toiletry, bath composition, food and drink, pharmaceutical) provided with a fragrance composition containing the foregoing compound as a fixative. It has thus been desired to develop and provide a novel fixative for the purpose of further improving fixing effects in fragrance compositions, expanding the variation of fixatives with respect to fragrance compositions or further enhancing diffusivity and long-lasting property of fragrance in products comprising various fragrance compositions incorporated therein.

[0004] An object of the invention is to provide a method which can provide improved diffusivity and long-lasting property of fragrance as compared with a method using conventional known fixatives and which enhance diffusivity and long-lasting property of fragrance without causing any safety problem, an agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition to be used in the method, a fragrance composition having an excellent diffusivity and long-lasting property of fragrance comprising the agent incorporated therein, and products such as cosmetic, toiletry, bath composition, food and drink and pharmaceutical having an excellent diffusivity and long-lasting property of fragrance comprising these ingredients.

SUMMARY OF THE INVENTION

[0005] The inventors made extensive studies of solution to the foregoing problems with the prior art. As a result, it was found that the incorporation of a compound represented by the following general formula (1) in a fragrance composition, the incorporation of a fragrance composition containing the compound of the general formula (1) in various products, or the incorporation of the compound of the general formula (1) together with a fragrance composition in various products during the preparation of these products makes it possible to obtain a fragrance composition having a remarkably enhanced diffusivity and long-lasting property of fragrance or various products having an excellent diffusivity and long-lasting property of fragrance. It was also found that products thus prepared have no safety problems. The present invention has thus been worked out.

DETAILED DESCRIPTION OF THE INVENTION

[0087] The term “fragrance” as used herein includes flavors and the term “fragrance composition” as used herein means a mixture of aroma components and includes flavor compositions. Accordingly, the term “fragrance” is synonymous with “flavor and/or fragrance” and the term “fragrance composition” is synonymous with “flavor and/or fragrance composition.

[0088] As mentioned above, a compound represented by the foregoing general formula (1) is used in the method for the enhancement of diffusivity and long-lasting property of fragrance according to the invention, the agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition according to the invention, the fragrance composition having an excellent diffusivity and long-lasting property of fragrance according to the invention, and the cosmetic, toiletry, bath composition, food and drink and pharmaceutical having an excellent diffusivity and long-lasting property of fragrance comprising these ingredients according to the invention. Examples of the compound represented by the general formula (1) include 2-(menthoxy)ethane-1-ol, 1-(menthoxy)propane-2-ol, 3-(menthoxy)propane-i-ol, 3-(menthoxy)propane-1,2-diol, 2-methyl-3-(menthoxy)propane-1,2-diol, and 4-(menthoxy)butane-1-ol.

[0089] A compound represented by the foregoing general formula (2) is preferably used as the compound represented by the general formula (1) to be used in the method for the enhancement of diffusivity and long-lasting property of fragrance according to the invention, the agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition according to the invention, the fragrance composition having an excellent diffusivity and long-lasting property of fragrance according to the invention and the cosmetic, toiletry, bath composition, food and drink and pharmaceutical having an excellent diffusivity and long-lasting property of fragrance comprising these ingredients according to the invention. Examples of the compound represented by the general formula (2) include 2-(l-menthoxy)ethane-1-ol, 1-(l-menthoxy)propane-2-ol, 3-(l-menthoxy)propane-1-ol, 3-(l-menthoxy)propane-1,2-diol, 2-methyl-3-(l-menthoxy)propane-1,2-diol, and 4-(l-menthoxy)butane-1-ol.

[0090] These compounds may be used singly or in combination of two or more thereof. These compounds are colorless substantially odorless oil-based materials and have an extremely high compatibility with ordinary fragrance compositions.

[0091] Particularly preferred among these compounds are 3-(menthoxy)propane-1,2-diol and 3-(l-menthoxy)propane-1,2-diol from the standpoint of long-lasting property in products such as cosmetic, toiletry, bath composition, food and drink and pharmaceutical. It was already known in JP-B-61-48813 (The term “JP-B” as used herein means an “examined Japanese patent application”), JP-A-47-16647, etc. that l-menthoxyether derivatives represented by the general formula (2), particularly 3-(l-menthoxy)propane-1,2-diol, have a cooling effect. In the case where the compound represented by the general formula (1) is a compound having a cooling effect, particularly where the compound represented by the general formula (1) is incorporated in products together with a fragrance composition during the preparation thereof, the diffusivity and long-lasting property of fragrance of the fragrance can be improved even if the compound represented by the general formula (1) is used in an amount less than the value by which the products provided with a fragrance composition are provided with a cooling effect. It is also known that 3-(l-menthoxy)propane-1,2-diol can be applied to a composition for inhibiting inflammation of throat and nose because of its cooling effect (WO 94/08550, WO 98/47483, WO 98/47482). It is further known that a compound represented by the general formula (2) can be incorporated in a food and drink, cosmetic, pharmaceutical or the like, singly or in combination with other compounds, to exert a cooling effect or plasticizing effect (JP-A-10-313819, JP-A-60-25908, JP-A-10-109945). However, there are no reports suggesting that compounds represented by the general formula (1), including those represented by the general formula (2), have an effect of remarkably enhancing diffusivity and long-lasting property of fragrance of fragrance compositions and diffusivity and long-lasting property of fragrance of various products.

[0092] The compound represented by the general formula (1) or (2) to be used in the invention is a known compound. The synthesis of the compound represented by the general formula (1) or (2) can be accomplished by utilizing any method disclosed in JP-B-61-48813, British Patent 1,315,626, JP-A-9-217083, etc., which is incorporated by reference herein.

[0093] In the invention, the amount of the compound represented by the general formula (1) or (2) to be incorporated in a fragrance composition or product and the method for applying the compound represented by the general formula (1) or (2) to the fragrance composition or product may be optimized depending on the kind and purpose of the fragrance or product in which the compound represented by the general formula (1) or (2) is incorporated. Particularly preferred examples of notes of the fragrance composition to which the agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition of the invention is applied include those having at least one note selected from the group consisting of floral, citrus, fruity, green, mint, herb, and marine (e.g., floral citrus green). Preferred notes include floral, citrus and fruity. Particularly preferred examples of floral notes include rose, muguet, lavender, lilac, carnation, and freesia notes.

[0094] The amount of the compound represented by the general formula (1) or (2) to be incorporated as an agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition when used in a fragrance composition is preferably from 0.01% by weight to 90% by weight, more preferably from 1% by weight to 50% by weight based on the total weight of the fragrance composition. The amount of the fragrance composition having an enhanced diffusivity and long-lasting property of fragrance provided by the addition of the agent to be incorporated in the product is preferably from 0.01 to 50% by weight, particularly from 0.1 to 30% by weight based on the total weight of the product.

[0095] On the other hand, the amount of the compound represented by the general formula (1) or (2) to be incorporated directly in various products is arbitrary depending on the form and purpose of the products. In practice, however, it is preferably from 0.0001 to 2.0 times, more preferably from 0.0005 to 1.5 times (by weight) the weight of the aroma composition and/or fragrance composition to be incorporated in the products. Most of the compounds represented by the general formula (2) have a cooling effect when applied to the skin or into the oral cavity. However, even when used in a concentration that gives no cooling effect, the compound of the general formula (2) can sufficiently exert the effect of the invention. For products which are externally applied to skin, scalp or the like, the compound of the general formula (2) can work even when used in an amount of less than 0.001% based on the total weight of the composition.

[0096] The compound of the general formula (1) does not show the cooling effect without depending on the concentration. The concentration wherein the compound of the general formula (2) in the products shows no cooling effect differs depending on the forms of the products and the methods for use. In general, in the products for direct use to the skin, scalp, etc. (e.g., the lotions described below, skin cosmetics described below, poultice pharmaceutical, hair cosmetics such as shampoo, rinse, conditioners, hair tonic, hair cream, etc., shaving foam, shaving gel, bath composition, soap, etc.), the concentration wherein the compound of the general formula (2) in the products shows no cooling effect is 0.1% (w/w) or less based on the total composition. In the products which are applied into the oral cavity (e.g., toothpaste, mouthwash, refreshing beverage, gum, candy, ice cream, sherbet, jelly, etc.), the concentration wherein the compound of the general formula (2) in the products shows no cooling effect is 0.001% (w/w) or less based on the total composition.

[0097] For the products which are not applied to the skin or scalp or into the oral cavity (e.g., detergent, softener, indoor aromatic, hair bleach, hair color, etc.), the amounts for use are as described above.

[0098] The product to which the invention is applied, e.g., cosmetic, toiletry, bath composition, food and drink, pharmaceutical may comprise arbitrary ingredients incorporated therein depending on the purpose besides the fragrance composition having an enhanced diffusivity and long-lasting property of fragrance of the invention or agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition of the invention.

[0099] The fragrance composition having an enhanced diffusivity and long-lasting property of fragrance of the invention comprises a compound represented by the general formula (1) incorporated therein as an essential ingredient. The fragrance composition having an enhanced diffusivity and long-lasting property of fragrance of the invention may further comprise ketones, aldehydes, esters, alcohols, ethers, terpenes, natural essential oils, synthetic musk or common materials constituting fragrance composition incorporated therein as necessary. The incorporation of the compound represented by the general formula (1) in the fragrance composition as an agent for the enhancement of diffusivity and long-lasting property of fragrance of an aroma component and/or fragrance composition makes it possible to remarkably enhance diffusivity and long-lasting property of fragrance, i.e., fragrance properties and fixation of the fragrance composition. Further, the incorporation of the fragrance composition having an enhanced diffusivity and long-lasting property of fragrance thus obtained during the preparation of products makes it possible to obtain products having improved diffusivity and long-lasting property of fragrance as compared with products comprising a compound represented by the general formula (1) directly incorporated therein.

[0100] In addition to the essential components of the present invention as described above, each of the cosmetic, toiletry, bath composition, food and drink and pharmaceutical may comprises a carrier, a diluent, etc. which is acceptable as a cosmetic, toiletry, bath composition, food and drink or pharmaceutical.

[0101] Examples of the cosmetic, toiletry, bath composition, food and drink and pharmaceutical as used in the invention include various lotions such as beauty wash, body lotion, after shave lotion and hair growth lotion, skin cosmetics such as milky lotion and cream, poultice pharmaceutical, pasting, hair cosmetics such as shampoo, rinse, conditioners, hair tonic and hair cream, perfume, Cologne, bath composition, soap, shaving foam, shaving gel, detergent, softener, indoor aromatic, toothpaste, mouthwash, ointment, refreshing beverage, gum, candy, ice cream, sherbet, jelly, and carbonated water.

[0102] The parts, ratios, percentages, or the like used in this specification are by weight.

[0103] The present invention will be further described in the following Examples and Comparative Examples, but the present invention should not be construed as being limited thereto.
